I am attempting to upgrade an older system with a AT/ATX Soyo SY-5EHM/5EH5 V1.1 Super 7 motherboard.  I have upgraded the Pentium 166 processor to an AMD K6-2 500 (used & purchased off eBay). This AMD CPU is on the approved upgrade list within the Soyo manual. I have reset all the required motherboard jumper settings to correspond with the AMD CPU and have added memory Dimms capable of 100mz bus speed, but the system will not post. I get nothing on the monitor. I have checked and double checked the jumper settings and have even reset them all back to the original settings, reinstalled the Pentium 166 CPU and booted it up to assure that the AGP video card was good. Before I assume the AMD processor is bad, my question is: The Mini AT Enlight PC case I am using only has a 200 watt(max)power supply. Is it possible that the motherboard and CPU are under
 powered, preventing a post. From what I can find the AMD CPU only requires 25 watts, so I'm preplexed.
